Application January 12, 1948, Serial No. 1,884

My invention relates to the art of door construction, and particularly concerns a device for conveying unhung doors and placing same in position for hanging within the door frame.

The principal object of my invention is to provide a, device adaptable to receive, support and clamp securely a door in a position whereby the door might be hung as by hinges within the door frame.

It is a further object of my invention to provide said device adaptable to receive and support a door during the planing of said door, the installation of hardware on said door and the like.

Another object of my invention is to provide my device as having means adapted to level the door before hanging in the proper position with respect to floor and door frame.

And a further object of my invention is to provide means on my device to raise the door preparatory to hanging to specified desired heights.

Further objects, advantages and features ap pear in the hereinafter annexed specification in which:

Figure 1 shows a perspective view of my door hanger and trolley.

Figure 2 shows a vertical sectional view thereof taken on the line 22 of Figure 3.

Figure 3 shows a side elevational view of my door hanger in place within a door frame with a door clamped therein.

Figure 4 shows a top view of my door hanger with a door clamp therein in the position which it might assume during the lining up and connecting together of hinge halves after each hinge half has been screwed in jamb and door respectively.

Figure 5 shows a detail section on line 5-5 of Figure 2.

Figure 6 shows a detail section of one of the clamping units of my door hanger.

Referring to the drawings, my device comprises a bed plate l8 having secured thereto in common fashion, as by welding, the angle irons I2 to which are welded vertically extending angle irons l4 and I5. Horizontal bracing member 16 is welded to the tops of the vertical members l5, and bracing members I 8 extend from the vertical members l5 to the vertical members 14. The structure thus described provides thus a horizontal channeled bed 20 and vertical supporting members into which may be slid a door 24. The bottom of the said door 24 rests upon the bed plate l0, and clamps 26 are provided to clamp the said door against adjacent members l4, l2, and I5, respectively.

1 Claim. (Cl. 214--1) The clamps 26 are supported in threaded bores 28 of the members l4 and I5 opposite their respective members just referred to, and comprise a threaded shaft 38, a handle disk 32, and a contact disk 34 which is secured to the shaft 30.

Extending horizontally from and welded to the vertical members I4 are two L-shaped supporting members 38, and likewise extending from and welded to the vertical members l5 are two L- shaped supporting members 38, the members 38 being supported by welded bracing members 40. As shown in Figure 5, at the extremity of each of the supporting members 36 and 38 is a threaded bore 42 into which is threaded a threaded screw shaft 44 having a bored periphery which receives the stub shaft 46 of a supporting member 48 for a roller 55, said supporting member 48 being provided with ball bearings 52. A disk-like handle 54 forms the top of each threaded shaft 44. Carried by each of the supporting members 36 and 38 and about the threaded shafts 44 are spacer collars 56 which engage lock nuts 58 which thread onto the threaded shafts 44. It will be noted that the handles 54 are welded atop the threaded shafts 44 after said shafts are threaded into the supporting members 36 and 38 and after the collars 56 and lock nuts 58 are in place.

Each of the horizontal angle iron members l2 carries a common carpenters level 68 parallel to itself and parallel to the bottom edge of the door being supported, while each of the supporting arms 38 likewise carries a carpenter's level 6! perpendicular to the door plane.

In operation, the door 24 is placed on the bed plate Ill and the clamps 26 are screwed into engagement with said door, clamping same securely against the members l4, l2, and I5. At

this point any door planing necessary may be done, hardware installed, and the like. When the door is ready for installation within its frame, the door is rolled by the rollers 50 adjacent said frame and aligned by means of the handles 54 which turn the threaded shafts 44. The bottom edge of the door may be adjusted to any desired distance from the floor and the door aligned to a true position with respect to the floor by adjustment of the handles 54 to balance the levels 60. By virtue of the levels 6|] parallel to the bottom and top edges of the door, the door is properly aligned with its vertical edges parallel to the vertical edges of the door frame, while by virtue of the levels 6| on the supporting members 38, the door plane itself may be made coincident with the hinge-side vertical edge of the door frame. This is to say that by properly leveling the two sets of levels the door may be rendered truly aligned with respect to the door frame. It is, of course, obvious that matching pairs of carpenters levels are not necessary and that there need be but one level parallel to the lower edge of the door and one level perpendicular to the plane of the door.

The door being properly aligned, its hinge-side edge may be brought adjacent the door frame and the'hingelhalves aligned as shown in Figure 4. The hinges being connected and the door hung, the clamps 26 may be loosened and the entire device rolled upon its rollers out from under the now freely supported door.

Having fully described my invention, it is to be understood that I do not wish to-be limited to the details herein set forth, ,but my.. nventi0n is of the full scope of the appended claim.

I claim:

A door supporting device comprising: a hori- .zontal bed; -vertical dooresupporting -mem-bers ,carried bysaid bed; clamping membersadapted .tosecure said dooriagainst. said vertical supporting members; a .framework ,carriedby. said horizontal bed.
